The Power of Megapixels

Higher resolution gives you the ability to enlarge an image and see critical details at a greater distance than before. The image above depicts the video image difference between various video streaming technologies. Analog systems typically provide top resolution of 960x480 pixels, significantly smaller than the image provided by HD Plus megapixel cameras. 1080p high definition is 1920x1080 pixels, similar to a 1080p HD television. AvertX 4MP cameras capture video at 2592x1520 pixels. That’s almost twice the number of pixels of 1080p!

Remote Controlled Autofocus 4x Optical Zoom

The AvertX HD820 dome cameras allow you to adjust the view and focus of your camera remotely without ever needing to climb a ladder. A fixed lens camera’s view is limited by how close or far it is from the targeted area. The HD820 with its 4x optical zoom gives you more choices for camera placement and to zoom in on what’s important to you. Once you have the view you want, autofocus gives you the sharpest picture possible.

HD820 IR

Superior Nighttime Performance

AvertX Cameras use the latest high intensity IR LED technologies for maximum visibility at night. Adaptive IR technology adjusts illumination levels as an object approaches to keep objects close to the camera from being overexposed and washed out.

*IR range and image quality can be affected by surfaces that absorb or reflect the IR light differently when in total darkness. Camera location or position may need to be adjusted to optimize the images. Some ambient lighting provides the best results for night surveillance.

Spectrum Vision WDR

Spectrum Vision True WDR (wide dynamic range) compensates for uneven light conditions caused by shadows, sun glare, back light and inconsistent lighting. Cameras with Digital WDR will show some improvement for these conditions but do not achieve optimum results. AvertX cameras with Spectrum Vision True WDR use multiple exposure technology that includes hardware and digital image processing. The result is superior video quality.

Extreme Cold

An internal heater allows this camera to operate in extreme cold temperatures down to -40°. The cold can cause other cameras to stop recording but an internal heater provides reliable operation through the winter or in other extreme environments such as cold storage freezers and refrigerators

Extreme Cold

Black Paintable Snap-on Cover

Instantly change the color of your AvertX dome camera with the included paintable snap-on cover. The black cover will match dark surfaces. If you would like a different color, paint the cover and snap it on. It’s that simple!

Your Video Safe And Secure

As an added layer of backup, AvertX cameras allow you to record directly to an internal microSD card. If your recorder is stolen, you can pull video directly from the camera’s microSD card.

* microSD card not included. See camera specifications for maximum storage card capacity and storage drive information.

HD820 Pain Free Installation

Pain Free Installation

AvertX has designed its system with integral features to simplify installation. An integrated PoE switch means you only need to run single cable your cameras. At startup, the ProConnect NVR recognizes your cameras and starts recording. The key to a successful installation is planning. Please visit our DIY Corner for resources to choose the appropriate system for your home or business and tips and tricks for installing and getting the most out of your system. If you have any questions about your installation, call the AvertX PRO Team!

Privacy Masks

Create a privacy mask on your AvertX camera to block recording and viewing of a designated area within the field of view of the camera. This feature allows you to block sensitive areas to protect privacy while still recording what is happening around it. A privacy mask gives you greater flexibility to place your cameras where they capture what you want, while maintaining the privacy or confidentially of assets, secure entry devices, documents, license plates, windows or areas where privacy is important.

All Weather Construction

AvertX cameras feature an IP66 rated housing construction to withstand tough weather conditions for outdoor installation. To provide even greater protection from the weather, this camera is equipped with an IP66 rated threaded connector and a matching IP66 connector on the included 100 foot Ethernet camera cable. This makes a water tight outdoor connection even when a protected connection is not possible.

ONVIF Compliant

ONVIF is an open industry association that provides and promotes standardized interfaces for effective interoperability of IP-based physical security products. AvertX HDIP cameras are ONVIF Profile S compliant and compatible with other ONVIF compliant recorders. Plug and Play automatic configuration is only available with AvertX HDIP recorders.

Note:

This camera is intended for Plug-n-Play use with AvertX’s current generation of ProConnect brand recorders. Use with other manufacturer’s recorders, and prior generation AvertX recorders, is not recommended without first contacting AvertX Pro Support. Additional advanced configuration and limitations such as continuous recording only may apply. See FAQs for steps. For previous generations of recorders, we strongly recommend the HD810 Dome Camera.
